Difference between a Simulink library and a model reference

What is the difference between a Simulink library and a model reference?

So far, I found 2 difference betweem them. is it right?

Reference

1.With model reference, you can also select acceleration methods

(it basically compiles the model)

=> performance improvement

2.Model references allow partial builds when using the coder product.

=> performance improvement

Library

-

Is there more difference about two except these?

Thank you

For Clarification, I used Libary for one function(like battery monitoring module) in a one project same as model reference.

Hi Jaeha

Yes, there are additional differences between "Simulink libraries" and "model references" beyond the ones you have mentioned.

Here’s a more comprehensive comparison:

Simulink Library:

1. Purpose: Reusable blocks for consistency across models.

2. Reusability: Centralized updates to library blocks affect all instances.

3. Customization: Limited to parameter changes unless link is broken.

4. Performance: No inherent performance boost.

5. Version Control: Easier for individual blocks.

Model Reference:

1. Purpose: Hierarchical model structuring for complex systems.

2. Modularity: Independent development and testing of components.

3. Performance: Supports acceleration and partial builds for speed.

4. Code Generation: Better for incremental code generation.

5. Encapsulation: Treats models as black boxes, reducing conflicts.

6. Version Control: Easier for entire models.

Hope this helps!
